To explore differences in fungal community structure and diversity in the rhizosphere soil of tea plants in tea gardens among different ages, the composition, alpha diversity, beta diversity, and group variability of fungal communities in the rhizosphere soil of 5-, 10-, 25-, and 40-year-old tea gardens (Y5, Y20, Y25, Y20) were studied using the Miseq platform. Results showed that the pH of the rhizosphere soil decreased as the age of the tea garden increased, while the soil nutrient content increased with age, except that this began to decrease in the 40-year-old tea garden. No significant difference in the fungal community’s alpha diversity was found in the rhizosphere soil among different tea garden ages. The structure and beta diversity of the fungal community in the rhizosphere soil of the 5- and 10-year-old tea gardens were similar to each other, as were those of the 25- and 40-year-old tea gardens. Certain dominant fungal species were most notably abundant in the rhizosphere soil of 5- and 40-year-old tea gardens. The order Sordariales accounted for 20.93% of fungi in the 5-year-old tea garden, and species of Trechisporales accounted for 14.97% of those in the 40-year-old tea garden. In addition, the rhizosphere soil of the tea gardens of different ages mainly contained fungi distributed among the Sordariales and Tremellomycetes orders. Overall, the fungal community in the rhizosphere soil of tea gardens of different ages was abundant overall and showed obvious differences in community structure among ages. The rhizosphere soil fertility and the amount of species in the fungal community increased with the age of the tea garden, favoring the increases in the populations of fungi that facilitate the growth and metabolism of tea plants.
